Description

Automatic recovery speed limit sorting coil, line

Technical field

The invention relates to a pipe and a wire, in particular to an automatic recycling pipe and a wire.

Background technique

At present, automatic recycling coils or winders are mainly in the form of spring-driven recovery and motor-driven recovery. The motor-driven retractable automatic winder realizes the retraction of the pipe or the wire by rotating the rotating disk of the motor. Since the motor-type automatic winding pipe and the wire machine require the motor to be powered, the structure is complicated, the cost is high, and an external connection is required. Power supplies, especially for the transport of flammable and explosive fluids, require an explosion-proof device. The spring-driven recovery automatic winder or winder is driven by the resilience of the crimping spring to drive the coil around the tube to retract the tube or wire. For example, Chinese patent, application number 20Q510060743. 9, February 2, 2006 discloses a power cord winder, which consists of a winding box, a coil spring assembly, a power cord assembly, an electrical connection assembly and a snap joint. Component composition.

The coil spring assembly comprises a coiled spring piece, and a central end of the coiled spring piece is fixed to the winding box by a crimping spring shaft core, and one end of the outer circle of the coiled spring piece is fixed on the reel. When pulling around the power cord wrapped around the reel, the reel rotates to drive one end of the reel spring in the reel to cause the crimping spring to be wound up to generate a crimping force. When the power cord is released, The retracting spring piece recovers the original shape and drives the reel to move in the opposite direction, so that the power cord is retracted on the reel.

The stop engaging assembly includes left and right friction plates, left and right spreaders, and a stop lever. The peripheral return spring is provided at the end of the stop bar, the extreme terminal extreme reset button and the button provided at the upper end of the stop lever. When the button is pressed, the stop lever is pressed, so that the stop lever presses the left and right spreader levers to open, so that the left and right friction plates are pressed against the inner wall of the reel, so that the reel is stopped, and the vertical binding posts are also Lower displacement, press the rotating winding bushing, and connect the power point contact. The button is a resettable button. When the power is pressed, the return spring acts elastically to make it return to the position when the button is pressed again. The button can also be used to control the rebound force to reach the control of the take-up speed.

As the coiled spring piece gradually restores the output torque, the angular speed of the reel becomes faster and faster, and as the number of wires wound on the reel increases, the diameter of the wrapable wire on the reel increases, making the reel The line speed is getting larger and larger, that is, the speed at which the power cord is recycled into the winder is increasing, which may endanger the safety of the user and cause damage to the winder and the connected tools. If the above-mentioned stopping device can only stop the reel by manual operation, or the progressive control of the resilience reaches the purpose of controlling the winding speed, the function and effect of automatic recycling will inevitably be lost. In addition, in the prior art, the winding pipe and the wire machine have a sorting function, but none of them have an automatic speed limit function.
